Incidence of Bilateral Scapholunate Dissociation in Symptomatic and Asymptomatic Wrists

The Journal of Hand Surgery, 05/25/2012

Bilateral radiographic Scapholunate dissociation (SLD) is much more common than previously assumed, is often asymptomatic, and does not inevitably lead to degenerative arthritis. These findings should call into question the assumption of a uniquely traumatic etiology. Further, most patients presented with pathologies unrelated to the scapholunate articulation. Surgical intervention chosen on the basis of radiologic findings, in the absence of clinical instability, might not be the best course of action, unless criteria are established to determine which patients eventually develop arthritic changes or become symptomatic.
